Liquid-filled forming method for rotary parts

Abstract

The invention provides a revolving body part liquid-filling forming device. The revolving body part liquid-filling forming device comprises a male die (1), a female die (3) and an edge pressing ring (2). The female die (3) is provided with a cavity (300) and a first liquid conveying pipeline (51), and the cavity (300) penetrates through the upper end face of the female die (3). A liquid containingspace is formed inside the cavity (300), and the first liquid conveying pipeline (51) communicates with the liquid containing space. A plate pressing gap is formed between the edge pressing ring (2)and the female die (3), and the height of the plate pressing gap can be adjusted. The edge pressing ring (2) is provided with a center through hole, and the male die (1) penetrates through the centerthrough hole to reach the interior of the liquid containing space. The invention further provides a forming method with the revolving body part liquid-filling forming device applied. The molded surface of the male die and the molded surface of the female die are matched to shape the final molded surfaces of deep drawn parts so that the shaping effect of liquid-filling pressure can be partially replaced, liquid-filling pressure is effectively reduced, and the product dimension precision is improved.

Description

technical field [0001] The invention relates to a soft mold forming technology, in particular to a forming process of a revolving body part, in particular to a liquid-filled forming method of a revolving body part. Background technique [0002] The variable curvature revolving body (revolving body revolving body whose section is composed of different radius arcs) is an important core part of the power system of aerospace products. Its structural feature is the revolving body parts composed of different curvature radii. Satellites play an important role. Due to the large variety of specifications, the required forming mold specifications are various. At present, the aerospace field adopts steel mold deep drawing technology for variable curvature rotary parts. Due to the existence of suspended areas, this technology often leads to local instability of the sheet metal and resulting in wall thickness. Defects such as thinning or wrinkling affect the uniformity of product wall t...

AI Technical Summary

Problems solved by technology

However, the structure provided by this patent document is prone to wrinkling and corrugation on the side wall during the deep drawing process of the steel mold, resulting in poor subsequent turning performance, and the steel mold is prone to problems of uneven wall thickness
